Find the distance from the line passing through points P(0,0,0) and Q(9,0,0) to the line passing through points R(3,-2,4) and S(
Alika [10]

Answer:

Step-by-step explanation:

Let the I line be PQ and II line be RS

Direction ratios  of PQ = (9,0,0) and direction ratios of RS = (0, -4, -12)

Distance between skew lines

=(a1-a2).(b1xb2)/|b1xb2|

where a1 and a2 are points

Here a1-a2 = (-3,2,-4) taking P and Q as points.

b1 = (9,0,0) and b2 = (0,-4,-12)

Shortest Distance = (a2-a1).(b1xb2)/|b1xb2|

De\left[\begin{array}{ccc}-3&2&-4\\9&0&0\\0&-4&-12\end{array}\right]

Numerator = -9(-24-16)=360

Denominator vector = i(0)-j(-108)+k(-36)

Modulus  of vector =\sqrt{108^2+36^2} =36\sqrt{10}

Hence Shortest distance = \sqrt{10}

The equation of line EF is y = 2x + 1. Write an equation of a line parallel to line EF in slope-intercept form that contains poi
77julia77 [94]

Answer:  The answer is (b) y=2x+2.


Step-by-step explanation:  The equation of a straight line in slope-intercept form is given by

y=mx+c, where, 'm' is the slope and 'c' is the y-intercept of the straight line.

The equation of the given line EF is

y=2x+1.

Here, slope, m=2 and y-intercept, c=1.

Since our new line is parallel to the given line, so the slope of the new line=m=2.

So, let the equation of the new line be

y=mx+d\\\\\Rightarrow y=2x+d.

Now, since the line passes through the point (0,2), so

2=2\times 0+d\\\Rightarrow d=2.

Thus, the equation of the new line parallel to line EF will be

y=2x+2.

The correct option is (b).
